The Path to Success – When drive and desire ride on the shoulders of opportunity of timing and execution. -Scott Grandfield


After facing many problems with ”so-called” tax professionals, we were left with the biggest IRS bill one can have in our business. Neglect and mismanagement left us in shambles. After calling a few EA’s I ran into David at Grandfield Tax, once we spoke I knew we found the right person for the task. Everyone else I had called was too robotic or displayed too much customary swagger. Thanks to the help of him and his firm, we are now on track with the IRS and things have fallen into place as they should have been from the very beginning. We at VC Construction are tremendously satisfied with Grandfield Tax services and we be looking to them for all our business tax and accounting needs.
